生态因子对银杏叶产量和黄酮含量的影响

Effects of habitat on Ginkgo in Leaf-Producing and flavonoid content

通过盆栽模拟试验,研究光照条件、土壤养分、土壤水分等因子对叶用银杏主要经济指标(叶产量、叶黄酮含量和产量)的影响。结果表明:随光照增强、土壤水分和土壤养分水平的升高,银杏产叶量升高。光照、土壤水分和土壤养分水平对银杏叶黄酮含量和单位营养空间黄酮总产量存在显著影响。光照越强、土壤水分和土壤营养水平越高,银杏黄酮含量和单位营养空间黄酮总产量越高。

Based on the simulated experiments,performed in plots,about the effect Of light intensities, soil moisture levels and soil nutrient levels on Ginkgo seedling in leaf-producing and flavonoid content ,conclusing can be drawn as follows： With the increase of light intensities,soil moisture and nutrient,the leaf biomass of Ginkgo seedlings increase. Light intensities, soil moisture levels and soil nutrient levels have a significant effect on the flavonoid content in Ginkgo leaves and total flavonoid yield in per unit area .In the experiments,the more flavonoid content in Ginkgo leaves and total flavonoid yield in per unit area increase.
